使用OpenXml操作Excel，实现Cell样式的设置

对于Cell的样式设置，网上已经有很多资料，下面供参考。

//添加SheetStyle：Font\Border\Fill\字体居中
Fonts fonts = new Fonts() { Count = (UInt32Value)2U, KnownFonts = true };
//fontId = 0
DocumentFormat.OpenXml.Spreadsheet.Font font = new DocumentFormat.OpenXml.Spreadsheet.Font();
DocumentFormat.OpenXml.Spreadsheet.FontSize fontSize = new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 15D };
FontFamilyNumbering fontFamilyNumbering = new FontFamilyNumbering() { Val = 1 };
FontScheme fontScheme = new FontScheme() { Val = FontSchemeValues.Minor };
font.Append(fontSize);
font.Append(fontFamilyNumbering);
font.Append(fontScheme);
fonts.Append(font);
//fontId = 1
font = new DocumentFormat.OpenXml.Spreadsheet.Font();
Bold bold = new Bold();
fontSize = new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 26D };
fontFamilyNumbering = new FontFamilyNumbering() { Val = 1 };
fontScheme = new FontScheme() { Val = FontSchemeValues.Minor };
font.Append(bold);
font.Append(fontSize);
font.Append(fontFamilyNumbering);
font.Append(fontScheme);
fonts.Append(font);
stylesPart.Stylesheet.Append(fonts);
